Is there a universal tool for managing and monitoring VPS, VDS, Dedicated via libvirt or ssh?

Question

OpenVZ

I am looking for a universal tool for managing / monitoring / alerting KVM, OPENVZ via linbvirt / ssh. Can you recommend something from the paid free?
Or a tool for managing/monitoring a server on linux via ssh?
It’s just that such utilities are stamped on android, but I didn’t find anything like that under native nix ...
